When does bill's approvalstatus change from pending approval to open

AI generated answer (using internal Slack threads):

The approval status of a bill in NetSuite changes from 'Pending Approval' to 'Open' when the bill has been approved. This is typically done by an authorized user or through a workflow process. Once a bill has been approved, it cannot be reverted back to 'Pending Approval' status natively within NetSuite. This is a default behavior and is designed to maintain the integrity of the approval process. However, it is possible to script around this limitation if necessary. Please note that the bill cannot be posted to the General Ledger (GL) until it has been approved. This is to ensure that only approved transactions impact the financial statements. If you notice that a bill with 'Pending Approval' status is impacting your accounts, it could be due to a custom approval status field overriding the native status. In some cases, there might be issues with the approval status not updating correctly due to timing issues or conflicts with other workflows or scripts. If this happens, you could try adding the status change on before load, or setting up a saved search or reminder to catch and manually fix these issues. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
